The scraper-blade E is or maybe of sheet The "frame-work B is an ordinary square metal, or wood with metal-cutting edges, as frame-work, and is mounted on the axle A, usual.

Z, respectively'. according to the form of scraper desired, one ioo 5o The timber D is hung directly under the set of irons of course being replaced by an pole O in Clovis-like devices D and D", the other, as the form of the scraper is changed.

The other or longitudinal part of said angleiron is flattened out and securely bolted to the under side of the timber D,directly under the axle A. 'Ihe ends of the scraper are connected with the ends of the cross-timber D3, on which the double-trees are mounted, by means of the rods E2 and E3, the rear ends of which are bent downwardly and extend down through the eyes e2 and es, respectively, thus firmly securing the scraper at both ends and in the middle directly to the draft devices of the machine.

The double-trees F are common doubletrees, and are secured to the cross-piece D3 by means of a pivot-bolt, f, in the usual man-- ner. When from any cause the draft is heavier on one side of the machine than the other, it can be readily equalized by withdrawing the pivot-bolt f and moving the double-trees to the proper side of the centerthe required distance, and until the hole in the center of said double-tree is directly over one of the holesd in the cross-piece, when the pivot-bolt is replaced and the double-trees thus secured in the required lposition to equalize the draft. By means of a series of holes, e, in the front end of the rod E3 the angleat which the rear half of the scraper-blade is set with reference to the road may be varied, if desired, as will be readily understood, and as shown bythe dotted lines in Fig. 2.

The levers G are mounted on suitable bearings, `(/,on the side pieces of the frame-work B in front of the axle A. They are provided with arms G,which extend out from the point where it is pivoted at nearly right angles with the main part of the lever. They are provided with ordinary spring-catches, g', which engage with the toothed sectors G3, and thus hold the lever in any desired position. rlhese springcatches are operated by means of the handlevers G2, to which they are connected by means of the rod g2. Vhen the scraper-blade is in the position shown,thc lever on the right hand of the machineis used to adjust the forward end, and is connected thereto from the end of the arm G by means of the rod G4. The left-hand lever is used to adjust the rear end of the scraper-blade. Its lower end is connected by the rod G5 to abell-crank lever, G, which is mounted on thc bearing b on the rear end of the side pieces, B, and is connected to the scraper by means of a rod, G7;

When it is desired to set the scraper-blade at the opposite angle from that shown, it can be readily done by changing the places of the rods E2 and E, and also exchanging the connecting mechanism of the levers, when the lefthand lever will connect with the forward end, and the right-hand lever with the rear end, the bell-crank lever GG being in such cases mounted on the bearing b on the right hand instead of on the left of the frame-work B, as will be readily understood.

When it is desired to change to a V-shaped scraper-blade, the long rod is taken out and a short one, similar to E2, is substituted, and

the mechanism of the lever on the left hand of the machine is dispensed with, and it is connected to the scraper, as is the right-hand 1ever, as shown.

The operation of my improved road scraper and leveler may be briefly recapitulated as follows: When it is desired to scrape the dirt from right to left, the scraper-blade is adj usted as shown, the holes e4 in the forward end of lthe rod E3 permitting the angle of the rear portion of the scraper-blade to be varied, if desired. When it is desired to scrape the dirt from left to right, the various connecting-rods are simply changed from one side to the other, as before described. When aV-shaped scraper-blade is desired, the long rod E3 is taken out, the several parts connecting the lever to the rear end of the blade are detached, the nuts which secure the hinge parts e are loosened, which permits them to slide upon the bolts by means of their slot-like holes, and thus the rear end of the scraper is permitted to swing forward'to the desired position when connecting-rods similar to those used on the oppositev side of the machine are substituted for those removed, and the" blade is ready for work. The varying draft is equalized in all cases by adjusting the double -trees upon the crosstimber D, as before described.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is-

l. .In a road scraper or leveler, a scraperblade having a joint in the center, by means of which it may be changed from a straight blade to a V-shaped blade, substantially as set forth.

2,. In'a road scraper or leveler, a scraperblade having a hinge in the center thereof, the

hinge parts being bolted to the back side of IOC) IIO

permit said scraper-blade to be swung back into a V-shaped blade, substantially as set forth.

3. The combination, in a road scraper and leveler, of the frame, the timber D, the clevislike devices D and D2, whereby said ktimber is prevented from lateral motion, but is rendered vertically adjustable, and the scraper E, secured to said timber, substantially as set 4. The combination, in a road scraper or leveler, of the timber D, to which the scraperblade is secured, and the clevis-like device D2, in which the rear end of said timber is mounted, whereby it is rigidly secured from any lateral movement, and at the same time rendered susceptible of easy vertical adjustment, substantially as set forth.

5. The combination, in a road scraper and leveler, of the frame, the timber D, the scraper` attached to said timber by iro'n E', and the clevis-like device D', in which the front end of said timber is mounted, provided with a series of holes, d, by means of which the front l end of said timber is secured at :my desired elevation, substantially as set forth.

6. The combination, in L road scraper and leveler, of the freine-Work, the verteallyud just-able timber D, the 'scraper-blade secured thereto, the cross-timber D, and the double trees mounted thereon, said cross-timber being provided with :L row of holes, d", by means of which said double-trees may be adjusted from side to side :1s the varying draft may require, substantially as set forth.

7. The combination, in a rood scraper and leveler, of the timber D, the cross-timber D, provided with holes 62.*', the @levis-like devices D and D2, for mounting said timber D, and the scraper-blade E, secured at its center to the under side of said timber, substantially us deseribed, and for the purposes speeiied.

S. rlhe Combination, in a road scraper and 2o leveler, of the scraper-blinde E, composed of two parts hinged together, the hinge-pntle E being` formed in the shape of en angle-iron, and its longitudine-l portion being securely bolted to the timber D, said timber, the eross- 2 5 timber D, the stavrods E? and E3, by means of which the ends ofthe Semper are connected to the ends ot said cross-timber, und thedouble-trees mounted thereon, substantially as described, and for the purposes specified. 3o

In witness whereof I have hereunto set my hr1-nd and .seal at Indianapolis, Indiana, this 11th day of August, A, D. 1833.
